Strong Authentication and Strong Integrity (SASI) Is Not That Strong

Download sites.uclouvain.be

In this work, we present a practical passive attack on SASI, an ultra-lightweight mutual authentication protocol for RFID. This attack can be used to reveal with overwhelming probability the secret ID of the prover by eavesdropping about 217 authentications. The result dismantles SASI and, more generally, provides a new approach that threatens ultra-lightweight authentication protocols. Key words: RFID, authentication, lightweight cryptography, privacy, passive attack
